305-044-556-504

Edgeboard Connectors Overview

The EDAC Inc. 305-044-556-504 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 20 positions with a 3.96 mm (0.156 inch) pitch and supports a maximum operating temperature of +105°C and a minimum of -40°C. The connector utilizes gold-plated copper alloy contacts housed in a green thermoplastic insulator. It is rated for 5 A current and offers an insulation resistance of 5 GOhms. The unit employs a solder lug termination method and is intended for panel mounting in a vertical orientation.

Edgeboard Connectors Feature Summary

Edgeboard Connectors Procurement Notes

Verify the specific contact termination style against project requirements, as datasheet variations may indicate solder pin or solder lug options for this series. Confirm that the panel mounting hole diameter matches the 3.96 mm specification to ensure proper mechanical fit. Ensure the selected variant aligns with the required RoHS compliance status before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a 20-position dual-row interface with a 3.96 mm pitch is required for vertical panel mounting. The 5 A current rating and wide operating temperature range make it suitable for robust industrial environments. Verify compatibility with the target PCB thickness and ensure the gold plating meets the necessary corrosion resistance standards for the application environment.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are characterized by their 3.96 mm pitch and dual-row design. The series provides various position counts and mounting configurations to support diverse electronic integration needs. The 305-044-556-504 specifically addresses applications requiring a 20-contact interface with high durability and precise alignment capabilities.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with identical 20-position counts and 3.96 mm pitch, such as 305-044-556-278, provided the termination style matches the assembly requirements. Cross-series replacements require verification of pitch, row count, and mounting dimensions to ensure mechanical and electrical compatibility.
